From 6d87103cae52e15ef1d73b9c2ad9404f9584ec31 Mon Sep 17 00:00:00 2001 From: "Paul N. Hilfinger" Date: Fri, 9 Jul 2004 19:29:56 +0000 Subject: Remove ARI problems: * ada-exp.y (write_var_from_sym): Reformat to put operator at beginning of line. * ada-lang.c (MAX_OF_SIZE): Rename max_of_size. Add comment. Add comment concerning MAX_OF_TYPE and MIN_OF_TYPE. (MIN_OF_SIZE): Rename min_of_size. Add comment. (UMAX_OF_SIZE): Renmae umax_of_size. Add comment. (UMIN_OF_SIZE): Remove. (max_of_type): New function to replace orphan macro in gdbtypes.h (min_of_type): Ditto. (discrete_type_high_bound): Use max_of_type. (discrete_type_low_bound): Use min_of_type. (possible_user_operator_p): Move operator to beginning of line. (ada_is_variant_part): Ditto. (ensure_lval): Rewrite to avoid deprecated operations. (ada_finish_decode_line_1): Use gdbarch_convert_from_func_ptr_addr rather than adding DEPRECATED_FUNCTION_START_OFFSET. (ada_enum_name): Remove assignments in 'if' statements. (build_ada_types): Add gdbarch parameter. (_initialize_ada_language): Replace deprecated_register_gdbarch_swap with gdbarch_data_register_post_init. Use add_setshow_uinteger_cmd rather than add_set_cmd and add_show_from_set. * ada-valprint.c (inspect_it): Remove declaration. (repeat_count_threshold): Remove declaration. (ada_print_floating): Remove assignments in 'if' statements. (print_str): Move operator to beginning of line. --- gdb/ada-lang.c | 122 +++++++++++++++++++++++++++++++++++++-------------------- 1 file changed, 80 insertions(+), 42 deletions(-) (limited to 'gdb/ada-lang.c') diff --git a/gdb/ada-lang.c b/gdb/ada-lang.c index ad5ec1c1365..2520b8efd99 100644 --- a/gdb/ada-lang.c +++ b/gdb/ada-lang.c @@ -623,30 +623,51 @@ ada_translate_error_message (const char *string) return string; } +/* Note: would have used MAX_OF_TYPE and MIN_OF_TYPE macros from + gdbtypes.h, but some of the necessary definitions in that file + seem to have gone missing. */ + +/* Maximum value of a SIZE-byte signed integer type. */ static LONGEST -MAX_OF_SIZE (int size) +max_of_size (int size) { LONGEST top_bit = (LONGEST) 1 << (size * 8 - 2); return top_bit | (top_bit - 1); } +/* Minimum value of a SIZE-byte signed integer type. */ static LONGEST -MIN_OF_SIZE (int size) +min_of_size (int size) { - return -MAX_OF_SIZE (size) - 1; + return -max_of_size (size) - 1; } +/* Maximum value of a SIZE-byte unsigned integer type. */ static ULONGEST -UMAX_OF_SIZE (int size) +umax_of_size (int size) { ULONGEST top_bit = (ULONGEST) 1 << (size * 8 - 1); return top_bit | (top_bit - 1); } -static ULONGEST -UMIN_OF_SIZE (int size) +/* Maximum value of integral type T, as a signed quantity. */ +static LONGEST +max_of_type (struct type *t) { - return 0; + if (TYPE_UNSIGNED (t)) + return (LONGEST) umax_of_size (TYPE_LENGTH (t)); + else + return max_of_size (TYPE_LENGTH (t)); +} + +/* Minimum value of integral type T, as a signed quantity. */ +static LONGEST +min_of_type (struct type *t) +{ + if (TYPE_UNSIGNED (t)) + return 0; + else + return min_of_size (TYPE_LENGTH (t)); } /* The largest value in the domain of TYPE, a discrete type, as an integer. */ @@ -664,7 +685,7 @@ discrete_type_high_bound (struct type *type) TYPE_FIELD_BITPOS (type, TYPE_NFIELDS (type) - 1)); case TYPE_CODE_INT: - return value_from_longest (type, MAX_OF_TYPE (type)); + return value_from_longest (type, max_of_type (type)); default: error ("Unexpected type in discrete_type_high_bound."); } @@ -682,7 +703,7 @@ discrete_type_low_bound (struct type *type) case TYPE_CODE_ENUM: return value_from_longest (type, TYPE_FIELD_BITPOS (type, 0)); case TYPE_CODE_INT: - return value_from_longest (type, MIN_OF_TYPE (type)); + return value_from_longest (type, min_of_type (type)); default: error ("Unexpected type in discrete_type_low_bound."); } @@ -3444,8 +3465,8 @@ possible_user_operator_p (enum exp_opcode op, struct value *args[]) || TYPE_CODE (TYPE_TARGET_TYPE (type0)) != TYPE_CODE_ARRAY)) || (TYPE_CODE (type1) != TYPE_CODE_ARRAY && (TYPE_CODE (type1) != TYPE_CODE_PTR - || (TYPE_CODE (TYPE_TARGET_TYPE (type1)) != - TYPE_CODE_ARRAY)))); + || (TYPE_CODE (TYPE_TARGET_TYPE (type1)) + != TYPE_CODE_ARRAY)))); case BINOP_EXP: return (!(numeric_type_p (type0) && integer_type_p (type1))); @@ -3535,24 +3556,36 @@ ada_simple_renamed_entity (struct symbol *sym) static struct value * ensure_lval (struct value *val, CORE_ADDR *sp) { - CORE_ADDR old_sp = *sp; - - if (VALUE_LVAL (val)) - return val; - - if (DEPRECATED_STACK_ALIGN_P ()) - *sp = push_bytes (*sp, VALUE_CONTENTS_RAW (val), - DEPRECATED_STACK_ALIGN - (TYPE_LENGTH (check_typedef (VALUE_TYPE (val))))); - else - *sp = push_bytes (*sp, VALUE_CONTENTS_RAW (val), - TYPE_LENGTH (check_typedef (VALUE_TYPE (val)))); + if (!
